A multi-strand nylon rope having improved abrasion resistance is comprised of a plurality of strands. Each strand is comprised of a plurality of yarns wherein each yarn is formed of a predetermined number of filaments. The filaments of each yarn are twisted together to form a yarn of a predetermined size, the twist direction being opposite that of the final ply yarn direction. For a right lay rope a sufficient number of filaments are twisted together in the left or "S" direction to produce a yarn of a predetermined size. Three or more yarns prepared in this manner are then plied or twisted together in the opposite or right direction. The cover for each strand is formed of alternate yarns of standard (i.e. round) and oblong filaments, respectively, the oblong filaments having a modification ratio of three, forming a rope having increased abrasion resistance, a hand and feel that is not stiff or unmanageable and which resists strand-to-strand wet abrasion.
A method for producing a multi-strand, all-nylon rope having superior resistance to abrasion and particularly wet abrasion, comprising the steps of:
